Just completed the upgrades of my Wordpress installation to Wordpress 2.2 for all the blogs I maintained – all 5 of them. The uploading part wasn’t that bad – I hated the part where I have to disable all the plugins before you start upgrading. I don’t mind if i have a short list of plugins – imagine having to disable & re-enable like 10 plugins each for 5 different blogs – it’s orgasmic. Anyway, i hope that would be a thing from the past with WP 2.2 – i can disable all plugins with just one click! 
Now, how does this widget-thingy work? Haven’t been playing with this….hmm…
Hehehe, I skali dump everything without disabling plugin or doing back-up, so far, no casualty. I did for the first three blogs then, got tired and decided to use the risky way.
lilian – it took me whole day to finish all 5 blogs, and now you telling me you just dump everything without disabling also can jalan. adoi…………
